.To ag-ZZ' whom it may concern/.

. Be it known that I, FRANK H. VANHOUTEN, of Fishkillon-the-IIudson, in the county of Dutchess and State of New York, have invented certain new and usefulglmprovernents 1n Oven-Doors; and I do hereby declare the following to be afull, clear, and exact descriptlon ofthe same, reference being had to the forming a part of this specification, and to the letters of refer- Y ence marked thereon. v Y y This invention relates to improvements in ven doors', more especially such as are used 1n bakers ovens, the objects'of the invention belng to provide a simple structure, which willlit tight or close the doorway completely,

- able form,

-. door closes to form a tight notlieliable to get out of order because of rough usage and variations in temperature to whlch 1t may be subjected, and further which will require little space in which to open and `w1ll not obstruct the doorway when opened.

Referring to the accompanying drawings Figure l 1s a front elevation of a door constructed in accordance with my invention.-

Fig. 2 .is a cross sectional view of the same taken 1n a plane from front to rear.

nike letters of reference in both the figures" indicate the same g parts. p

In carrying the invention into practice in the most simple, and as I consider it, prefer- I provide a rectangular frame or lamb lettered A in the drawings, of convenieni size for the oven of which it lislto form a par For convenience in building the frame rin wlth the brick work, it is provided with a wide Iiat base and a web B extending up around on the outside.

The frame is preferably made of somewhat greater height than the door opening proper, and a depending web C, is provided, having a peep opening or window at the center, closed by a pane of transparent material through whlch the interior of the oven may be inspected, and a forwardly projecting bearing surface E at the bottom against which the ently appear,

In doors intended for ovens, diiiiculty has been experienced because of the wearing of the supporting bearings which causes the door joint as will pres- I to fit unevenlyzin` the opening,thereby leav- 'ing cracks, &c., making the oven inefficient,

and it is one of my principal objects to overcome this andother difficulties of a likev nature. For this purpose, I form .the door Gto kswing on horizontal centers and count'erbal-- Iwith its horizontal centers, thus when in closed position as shown in Fig. 2, the greater 'portion of the weight is back of the centers keeping the door` closed tightly against the sill at the bottom and against the bearing surface E at the top of the door opening.

` On the sides or jambs of the door frame, I form or attach horizontal bearing surfaces K, lextending rearward parallel with the plane of movement of the door and upon the ends of the door I form or attach segments. L ladapted to rest on the straight bearing sur# faces and form the supports or bearings for thedoor. VThe contact of the surfaces is a rollingcontact as the door is opened or closed, and thus there is little or no wear.

To prevent any upward movement of the door, overhanging straight bearing surfaces K are provided against the under side of which the pintles L take a bearing should the door tend to ride up.

Inasmuch, as under some circumstances it may be found desirable to provide a means for preventing the door from' getting out of alignment when being moved, I attach racks O. to the bearings K, and gear segments P to the other segments VL for meshing with said racks, as shown in Fig. 2, thus' even during its swinging movements the door is held in its proper seat when closed. l

A stop surface Q is provided at the extreme lower portion of the central web for limiting the opening ofthe door (see dotted lines Fig. 2).

IOO

A door constructed in accordance with this invention it will be seen, may be easily fitted, there are no loose parts to become lost or broken, and the manipulation is very easy, inasmuch, as the parts are so evenly balanced that when started the door will almost move of itself. The balance weight is made adjustable in order to insure a proper balance of each particular door, thus insuring a proper balancing of each door irrespective of the character of the castings.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a door for bakers ovens, the combination with the frame having the straight horizontal bearing surfaces at each side, and running in a direction from front to rear of the door opening, of the weighted door having the segmental bearings resting and rocking on the straight bearings at the sides of the door frame; substantially as described.

2. In a door for bakers ovens, the combination, with the door frame having the bearings at each side, of the centrally pivoted door supported on said bearings andthe weight on the upper end of the door working from one side to the other of the axis of rotation of the door, whereby the center of gravity is thrown on one orthe other side of said axis, and the dooris held in opened or closed position as the'case may be; substantially as described.

3. In a door for bakers ovens, the combination with the frame having the internal depending web and bearings at each side, of the doorsupported on said bearings to swing on the horizontal axis, and co-operatin g with the depending web and bottom of the frame to close the 'door opening, and the weight on the upper end of said door, working trom one side to the other of theaxis of the door, whereby the center of. gravity is shifted and the door held in open or closed position as the case may be; substantially as described.

4. In adoor for bakers ovens, the combination with the door frame having the depending web and the horizontal bearing surfaces extending from front to rear at each side, of the door tting against the depending web and base of the frame to close the door openadjustable weight on the lower portion of the door; substantially as described.

6. In a door for bakers ovens, the combination with the frame having the horizontal bearings at each side and running in a direction from front to rear of the door opening and rack bars as described, of the door having the centrally arranged segmental rack and bearings as described, co-operatingwith and rocking on the racks and bearings on the sides of the door, to hold the door in line While being opened and shut; `substantially as described. p Y

7.. In a door for bakers ovens,'the combination with the frame having the two horizontal bearings extending from front to rear at each side, ofthe door having the centrally arranged segments resting on `the lowermost bearings'at each side, and the pintles co-operatin g with the under side of the upper bearings to prevent the-vertical displacementof thel door substantiallyas described.

8. In a doorforbakers ovens, the combination with vthe frame having the bearings at each side, ot' the door centrally pivoted in said bearings and having theupper portion cut away to admit of the formation of a'window lor peep opening below the level of the'upper edge of the door; substantially as described.

9. In a door for bakers ovens, the combination with the frame having the ydepending web provided with a central window or peep lopening, the centrally pivoted door turning on ahorizontal axis and having the center of its upper portion cut way over the window or vpeep opening; substantially as described.
